Summary This paper analyzes the reference tracking behavior of Buck converters using several control schemes including voltage-mode, current-mode and V(2)-control from both large-signal and small-signal domains. Loop gains applicable to reference tracking are highlighted, and reference-to-output transfer functions are derived for the cases when end-point Prediction (EPP) is applied to enhance the response. A novel V(2)-controlled Buck converter with EPP is fabricated. The measured reference tracking response shows 10 times improvement in speed.
